OAKLEY T. BROWN, 0F AUDUBON, NEW JERSEY, ASSIGNOR r0 CAMDEN IRON WORKS,

A CORPORATION OF NEW JERSEY.

GAS-PRODUCER CONSTRUCTION.

Application filed July 3, 1920. Serial No. 393,866.

To all 10 7mm. it may Concern Be it known that I, OAKLEY T. BROWN, a citizen of the United States, residing at Audubon, in the county of Camden and State of New Jersey have invented a certain new and useful tion, of which the following is a specification.

My invention relates to the construction of gas producers, whether they be operated under pressure or vacuum conditions.

The purpose of my invention is to support the top plate or cover plate from a point or points inside the edges and preferably from the center, allowing free expansion about the edges.

A further purpose is to-provide triangular beam mounting for the stirring mechanism and also for thetop' plate.

Further purposes will appear in the specification and in the claims.

I have preferred to illustrate my invention by but one type thereof, selecting a type which has been found to be practical, eflicient and reliable and which at the same time well illustrates the principles of my invention.

Figure 1 is a top plan view of a gas producer to which my invention may be applied.

Figure 2 is a vertical section of Figure 1 upon the line 22.

Figure 3 is a perspective of the parts forming the center of the beam position, ready for assemblage.

In'the drawings similar numerals indicate like parts.

The general construction of the gas producen shown is old, corresponding to a well known type of pressure producer manufactured and catalogued by Camden Iron lVorks and will be sufficiently understood by those skilled in the art so that only a very general description of it need be given.

The casing 5, lined at 6 is rotated upon rollers 7 through a worm gear 8 and worm 9, driven by a motor 10 through gearing 11. At the upper end, the shaft 12 operates stirring and feeding mechanism through gearing 13 and the transverse shaft 14.

The fire brick 15 of the dome is supported directly by flanges 16 from a, fixed cylindrical shell 17 which dips at 18 into a water seal 19 within the as-Producer Construo in separated V casing, the weight of the shell and dome being supported by brackets 20 from the side standards or uprights 21.

The standards 21 support beams 22 here shown as three in number, of a star beam. The individual beams of. the star are made up of top and bottom channels 23, 24, which are connected by lattice work 25 and which at the center are united by top and bottom gussets 26, 27 and by side gussets 28.

One of the beams is shown as supporting the bearings 29 for the shaft 14. It also supports the worm gears 30 (one only shown) upon this shaft, worms 31 (one'only shown) and the stirrers 32, 33 for the producer. These stirrers are-mounted in supports 34, 35, one pair of which is mounted .upon a gusset 28'and the other upon an additional or extended side gusset 36. The stirrers are cooled through inlet and outlet fluid connections at 37, 38.

The stirrers are water sealed at 39 through flanges 40, mounted upon the stirrers and annular cups 41 upon the top plate 42. The top plate in the illustration is apertured for gas outlet 43 and also carries an automatic sealing coal feed 44 driven through the gearing 45, 46, 47 and 48, from the shaft 14. The detail of this feeding mechanism and the cooperative relation between this feed and the stirrers are described at length by me and claimed in a copending application.

Instead of securing the top plate 42 at or near the circumference I support it at an interior point, preferably at the middle where, in the construction illustrated, it is mounted upon the bottom flange 49 of a spool 50 whose top flange 51 is secured to the under gusset plate 27. The outer edge of the plate is flanged at 52 and is sandsealed at 53 within an annular groove formed between flanges 54 and 55 so as to maintain a constant seal at this point at the same time that the top plate is free to expand and contract as the temperature changes require.

It will be evident that the beam construction and top plate support may be carried out in different ways than those shown, without departing from the spirit and scope of my invention and it is my purpose to cover herein all such changes and alterations.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is i 1. A gas producer having a rotary body and fixed top construction, driving mechanism therefor, standards at the side of the producer, stirring mechanism therefor and a triangular beam support for said stirring mechanism.

2. A gas producer having a rotary body and fixed top construction, driving mechanism therefor, standards at the side of the producer, stirring mechanism therefor and beam support for the mechanism comprising top and bottom central gussets, side gussets and top and bottom channels extending from the top andbottom central gussets to the standards at the sides of theproducer.

3. A producer having a rotary body and fixed top construction, driving mechanism therefor, standards at the side of the producer, stirring mechanism therefor, top

and bottom central gussets, top and bottom channels secured thereto and to the standards, and side gussets secured to the channels and uniting the top and bottom channels and gussets.

4. A gas producer having a rotary body and fixed top construction, driving mechanism therefor, standards at the side of the producer, stirring mechanism therefor and a supporting beam comprising top and bottion, a fixed cover therefor and a top plate,

for the cover in combination with side supports, connections between the side supports and the cover at a distance from the perimeter of the cover and a sand seal for the top plate; I

7. In a gas producer, a rotatable body portion and a fixed roof therefor in combina-' tion with a top plate for the roof, a central support for the top plate and a sand seal between the perimeter of the top plate and the casing. V r

8. A fixed gas producer roof'anda top plate therefor in combination with support for the plate from above at a distance from the perimeter of the plate and means for sealing the perimeter of the top plate against gas leakage between it and the roof.
